Geant4 9.4 - patch-02 Release Notes
|
|
-----------------------------------
|
|
|
|
24 June 2011
|
|
|
|
List of fixes included in this public patch since the public release 9.4.p01:
|
|
|
|
o Configuration:
|
|
-------------
|
|
+ CMake scripts:
|
|
o Added G4VERBOSE compilation option as default, replicating behaviour
|
|
of the standard Makefiles. The user can disable the option to remove
|
|
the definition from the compile flags.
|
|
o Make installation of examples optional. Addresses problem report #1205.
|
|
o Added G4_STORE_TRAJECTORY to global compile definitions.
|
|
Addressing problem report #1208. As 'advanced' option users can choose
|
|
not to store trajectories; by default this option is set to ON,
|
|
replicateing behaviour of the standard Makefiles.
|
|
o Added .svn to list of patterns to exclude when installing directories.
|
|
o Abilitated support for RayTracerX visualization driver.
|
|
+ Configure script:
|
|
o Corrected settings of G4LIB_USE_DLL for the case of DLLs build on
|
|
Windows. Partially addressing problem report #1189.
|
|
o Fixed detection of Qt4 and forbid use of Qt3.
|
|
+ Workaround in binmake.gmk to avoid clashes with flag LDFLAGS set in the
|
|
user's environment beforehand.
|
|
+ Fixed limitation of string argument length in liblist.c program.
|
|
Addressing problem report #1033.
|
|
|
|
o Digits_Hits:
|
|
-----------
|
|
+ Fix in G4PSCylinderSurfaceFlux and G4PSSPhareSurfaceFlux for the way
|
|
how flux is scored.
|
|
+ Fixed scorers used for cylindrical mesh that require cubic volume
|
|
or surface area.
|
|
+ Fixed scoring meshes for visualizing scores of very few entries.
|
|
|
|
o Error Propagation:
|
|
-----------------
|
|
+ Backport a fix to G4ErrorSymMatrix to address issues on Windows.
|
|
+ Fixed cases of variables set but not used.
|
|
|
|
o G3toG4:
|
|
------
|
|
+ Fixed signature in functions of G4gs* classes to be 'G4String *'
|
|
(was G4String[]) as used in clparse. Fixes Windows linking problem.
|
|
+ Fixed cases of variables set but not used.
|
|
|
|
o Geometry:
|
|
--------
|
|
+ Fixed cases of variables set but not used.
|
|
+ magnetic_field:
|
|
o Reordered data members to group invariants, field parameters, etc...
|
|
+ management:
|
|
o Fix in G4LogicalVolume::AddDaughter() for proper propagation settings
|
|
of local field manager. Avoid forcing propagation to all daughters when
|
|
a local field manager is set already for the new daughter.
|
|
Addressing problem report #1183.
|
|
o Use internal header for physical constants in meshdefs.h.
|
|
+ navigation:
|
|
o Adjusted constructor in G4PropagatorInField to reorder data members.
|
|
o Some code cleanup.
|
|
+ solids/Boolean:
|
|
o Added protection for potential cases of infinite loop in
|
|
DistanceToIn(p,v) and related error message with event abortion.
|
|
+ solids/BREPS:
|
|
o Use G4Transform3D typef in signature, where applicable.
|
|
+ solids/CSG:
|
|
o G4Tubs: use safe formula for quadratic equation solution, to better
|
|
handle numerical errors.
|
|
o G4Torus: use relative radial tolerances to avoid loss of precision
|
|
issues for shapes of big dimensions. Addresses problem report #1175.
|
|
o Added protection for potential negative argument to sqrt() in
|
|
CalculateExtent() for G4Orb, G4Cons and G4Sphere.
|
|
Made radial tolerance a local constants in G4Orb and G4Sphere.
|
|
+ solids/specific:
|
|
o G4ExtrudedSolid: fix in Inside(p) for false overlap reporting.
|
|
Addressing problem report #1211.
|
|
o Use internal typedefs for CLHEP types, where applicable.
|
|
|
|
o Global:
|
|
------
|
|
+ Fixed internal copy constructor in G4PhysicsVector.
|
|
+ Added G4 internal types to CLHEP classes.
|
|
+ Use G4UniformRand() in G4Poisson.
|
|
+ Changed date for patch-02 to release 9.4.
|
|
|
|
o Graphical Representations:
|
|
-------------------------
|
|
+ Fixed more minor Coverity reports.
|
|
|
|
o Interfaces:
|
|
----------
|
|
+ Fix in G4VBasicShell::ApplyShellCommand() for substring exact
|
|
comparisons; addressing problem report #1180.
|
|
+ Removed obsolete Qt3 code and avoid inclusion of OGL flags in
|
|
compilation.
|
|
|
|
o Particles:
|
|
---------
|
|
+ Fixed energy of proton and neutrino in G4NeutronBetaDecayChannel.
|
|
+ Modified PDGCodeChecker to allow setting of PDG code for neutron balls.
|
|
+ Fix in G4ParticleDefinition::SetApplyCutsFlag() to get rid of
|
|
unnecessary warning messages for proton.
|
|
+ Fixed Coverity reports, and cases of variables set but not used.
|
|
|
|
o Persistency:
|
|
-----------
|
|
+ G4GDMLWriteMaterials: avoid dereferencing of null pointer in
|
|
PropertyWrite() for materials without property assigned; issue a
|
|
warning message. Addressing problem report #1214.
|
|
+ Use internal typedefs for CLHEP types, where applicable.
|
|
+ Fixed cases of variables set but not used.
|
|
|
|
o Electromagnetic Processes:
|
|
-------------------------
|
|
+ Adjoint:
|
|
o Fixed cases of variables set but not used.
|
|
+ Polarisation:
|
|
o Safer computation of a normal in G4PolarizationHelper.
|
|
o G4ePolarizedIonisation: cleared use of obsolete MinCutEnergy() method.
|
|
o Fixed cases of variables set but not used.
|
|
+ Standard:
|
|
o G4IonFluctuation: replaced Gauss sampling by Gamma function sampling
|
|
for large step; important for stable sampling of struggling of range
|
|
and energy loss of low-energy ions.
|
|
o G4GoudsmitSaundersonMscModel: fixed computation of mean energy at
|
|
a step for large steps; fixed computation of mean scattering angle.
|
|
+ Utils:
|
|
o G4EmModelManager, G4EmCalculator: changed smoothing function
|
|
between two models; effect is seen for protons in non-NIST water.
|
|
o G4VEnergyLossProcess: start cross-section table from energy threshold
|
|
for given cut value, so lowest cross-section is zero only for the
|
|
first element of the table. Number of bins per decade is not changed,
|
|
total number of bins is reduced. The fix improves the Spline
|
|
interpolation of the cross-section.
|
|
o G4VEmModel: use linear interpolation for G4EmElementSelectors to avoid
|
|
numerical imprecision for small number of bins (increase number of
|
|
bins will require extra memory).
|
|
+ Xrays:
|
|
o Fixed Coverity reports.
|
|
o Fixed cases of variables set but not used.
|
|
|
|
o Hadronic Processes:
|
|
------------------
|
|
+ cross_sections:
|
|
o G4TripathiLightCrossSection: return 0 cross-section in method
|
|
GetZandACrossSection(), when E_cm <= DBL_MIN.
|
|
Addressing problem report #1174.
|
|
+ models/cascade:
|
|
o G4InuclNuclei: removed prefatory message about PDGencoding.
|
|
o G4ElementaryParticleCollider: added protection in sampleCMcosFor2to2()
|
|
to avoid case of divide-by-zero.
|
|
+ models/CHIPS:
|
|
o Fixed case of double-delete in G4QFragmentation::Breeder().
|
|
Addresses problem report #1179.
|
|
+ models/high_energy:
|
|
o Fixed cases of variables set but not used.
|
|
+ models/im_r_matrix:
|
|
o Fixed cases of variable set but not used in G4XPDGElastic.
|
|
+ models/low_energy:
|
|
o Fixed case of variable set but not used in G4LCapture.
|
|
+ models/neutron_hp:
|
|
o Added "Fermium" in G4NeutronHPNames and fixed bug in "Actinium".
|
|
o Bug fix in G4NeutronHPDiscreteTwoBody for MF=6, LAW=2 case.
|
|
o Added message where environment variable "G4NEUTRONHP_NEGLECT_DOPPLER"
|
|
is activated.
|
|
+ models/pre_equilibrium:
|
|
o Fixed cases of variables set but not used.
|
|
+ models/radioactive_decay:
|
|
o Fixed memory leak in G4RadioactiveDecay::AddDecayRateTable().
|
|
o Fixed array overrun in G4RadioactiveDecay::SetSourceTimeProfile() and
|
|
SetDecayBias(). Avoid possible dereferencing of zero pointer in
|
|
DecayIt() when in branching-ratio bias mode, fill 'tempprods' as if
|
|
no biasing is active.
|
|
o Removed unnecessary warning and added a check for maximum shell number,
|
|
in G4NuclearDecayChannel.
|
|
o Initialize static data in G4RadioactiveDecayRate constructor.
|
|
and array data in G4RadioactiveDecay::LoadDecayTable().
|
|
o Fixed cases of variables set but not used.
|
|
+ stopping:
|
|
o Fixed cases of variables set but not used.
|
|
|
|
o Generic Processes:
|
|
-----------------
|
|
+ Cuts:
|
|
o Fixed defects reported by Coverity.
|
|
o Fixed cases of variables set but not used.
|
|
+ Management:
|
|
o Fixed cases of variables set but not used.
|
|
o Fixed defects reported by Coverity.
|
|
+ Scoring:
|
|
o Fix in G4ScoreSplittingProcess::PostStepDoIt() to not consider steps
|
|
if the voxel boundary is not skipped. Addressing problem report #1209.
|
|
o Added IsAtRestRequired() method to G4ParallelWorldScoringProcess.
|
|
+ Transportation:
|
|
o Fix G4Transportation::AlongStepDoIt(): use only initial velocity to
|
|
update time. Results in one less sqrt() per tracking step.
|
|
|
|
o Run:
|
|
---
|
|
+ Ensure that a ScoreSplittingProcess is added only once in
|
|
SetScoreSplitter() of G4RunManagerKernel. Addresses problem report #1218.
|
|
|
|
o Track:
|
|
-----
|
|
+ Set maxT for Velocity Table to 1000. Added SetVelocityTableProperties().
|
|
Addresses problem report #1185.
|
|
+ Fixed some problems reported by Coverity.
|
|
|
|
o Tracking:
|
|
--------
|
|
+ Fixed setting of 'fWorldBoundary' step status in G4SteppingManager
|
|
InvokePostStepDoItProcs() and DefinePhysicalStepLength(). Flag was not
|
|
set and not used.
|
|
|
|
o Visualization:
|
|
-------------
|
|
+ HepRep:
|
|
o Use internal G4RotationMatrix typedef in G4HepRepFileSceneHandler
|
|
instead of native CLHEP type.
|
|
o Correction in GNUmakefile.
|
|
+ OpenGL:
|
|
o Re-instated cutaways in intersection mode in G4OpenGLViewer, which
|
|
was apparently commented out accidentally in 9.4.
|
|
+ RayTracer:
|
|
o Trap recursive calls in G4RayTracerViewer::DrawView(), thus avoiding
|
|
warning messages for each pixel when endOfEventAction() is "refresh".
|
|
o Fixed some Coverity warnings; fixed CMake scripts.
|
|
|
|
o Examples:
|
|
--------
|
|
+ Updated reference outputs.
|
|
+ extended/eventgenerator/HepMC/MCTruth:
|
|
